Python: Python is known for its simplicity and readability, making it a popular choice for back-end development. It offers frameworks like Django and Flask that simplify web development. 3. Ruby: Ruby is a dynamic, object-oriented language that is often used with the Ruby on Rails framework. It emphasizes convention over configuration, making it efficient for rapid development. 4. PHP: PHP is a server-side scripting language that is widely used for web development. It has a large community and offers frameworks like Laravel and Symfony. 5. Node.js: Node.js is a JavaScript runtime built on Chrome's V8 engine. It allows developers to use JavaScript for both front-end and back-end development, making it a popular choice for full-stack development. 6. C#: C# is a versatile programming language developed by Microsoft. It is commonly used for back-end development with the .NET framework, providing a robust and scalable environment. 7. Go: Go, also known as Golang, is a statically typed language developed by Google. It is known for its simplicity, efficiency, and built-in support for concurrency, making it suitable for high-performance back-end systems. 8. Rust: Rust is a systems programming language that focuses on safety, speed, and concurrency. It is gaining popularity for back-end development due to its memory safety guarantees and performance optimizations. 9. Scala: Scala is a statically typed language that runs on the Java Virtual Machine (JVM). It combines object-oriented and functional programming paradigms, making it suitable for building scalable and high-performance back-end systems. 10. Kotlin: Kotlin is a modern programming language that runs on the Java Virtual Machine (JVM). It offers concise syntax, null safety, and interoperability with Java, making it a popular choice for back-end development
